May help manage blood sugar
Purple yam flavonoids have been found to help reduce blood sugar levels in people with type 2 diabetes. Obesity and oxidative stress-induced inflammation raise your risk of insulin resistance, poor blood sugar management, and type 2 diabetes. Insulin resistance occurs when your cells do not respond adequately to the hormone insulin, which is in charge of blood sugar management. In one test-tube investigation, flavonoid-rich purple yam extracts lowered oxidative stress and insulin resistance by preserving pancreatic insulin-producing cells. Furthermore, a research of 20 rats discovered that giving them larger doses of purple yam extract reduced hunger, stimulated weight reduction, and improved blood sugar management.
Finally, another study found that a purple yam supplement slowed blood sugar absorption in rats with high levels, resulting in better blood sugar management. This is most likely owing to purple yams' low glycemic index (GI). The GI, which runs from 0 to 100, measures how quickly carbohydrates are taken into circulation. Purple yams have a GI of 24, which means that carbohydrates are slowly broken down into sugars, resulting in a consistent release of energy rather than a blood sugar rise.
